Power goes out for 20 minuts after 20 minuts come back

Power goes out for 20 minuts come back on should just replace it the bracker?

Why a braker heating up causing the circuit to shut down when it cold off the power comes back on

Sounds like a breaker heating up and causing the circuit to shut down then when it cools off it comes back on. If this continues for much longer I'd definitely suggest calling in an electrician to pin point the problem. You could have a potential fire hazard on your hands.

The breaker could be old, or there may be too much draw on the breaker, at full usage have you tested the amp draw
